ppmdim - dim a portable pixmap down to total blackness
ppmdim
dimfactor [ppmfile]
Reads a portable pixmap as input. Diminishes
its brightness by the specified dimfactor down to total blackness. The dimfactor
may be in the range from 0.0 (total blackness, deep night, nada, null, nothing)
to 1.0 (original picture's brightness).
As pnmgamma does not do the brightness
correction in the way I wanted it, this small program was written.
ppmdim
is similar to ppmbrighten , but not exactly the same.
